The

router

automatically detects the information in the following fields:

•

Router’s IPv6 Address on WAN

.This field shows the IPv6 address that is acquired for the

router

’s

WAN (or Internet) interface. The number after the slash (/) is the length of the prefix, which is also

indicated by the underline (_) under the IPv6 address. If no address is acquired, the field displays

Not Available.

•

Router’s IPv6 Address on LAN

.This field shows the IPv6 address that is acquired for the

router

’s

LAN interface. The number after the slash (/) is the length of the prefix, which is also indicated by

the underline (_) under the IPv6 address. If no address is acquired, the field displays Not Available.

6.

(Optional) In the

User Class (If Required)

field, enter a host name.

Most people can leave this field blank, but if your ISP gave you a specific host name, enter it here.

7.

(Optional) In the

Domain Name (If Required)

field, enter a domain name.

You can type the domain name of your IPv6 ISP. Do not enter the domain name for the IPv4 ISP here.

For example, if your ISP’s mail server is mail.xxx.yyy.zzz, type xxx.yyy.zzz as the domain name. If

your ISP provided a domain name, type it in this field. For example, Earthlink Cable might require a

host name of home, and Comcast sometimes supplies a domain name.

Set Up an IPv6 6rd Tunnel Connection

The 6rd protocol makes it possible to deploy IPv6 to sites using a service provider’s IPv4 network. 6rd

uses the service provider’s own IPv6 address prefix.This limits the operational domain of 6rd to the service

provider’s network and is under direct control of the service provider. The IPv6 service that is provided is

equivalent to native IPv6.

The 6rd mechanism relies on an algorithmic mapping between the IPv6 and IPv4 addresses that are

assigned for use within the service provider’s network. This mapping allows for automatic determination

of IPv4 tunnel endpoints from IPv6 prefixes, enabling stateless operation of 6rd.

To set up an IPv6 6rd tunnel connection:

1.

Launch a web browser from a computer or WiFi device that is connected to the network.

2.

Enter

.

A login window opens.
